A year ago, with the launch of the Galaxy S7, DisplayMate said Samsung’s 2016 flagship device had the best smartphone display available. Now, get ready for a shocker, DisplayMate is back, this time declaring that the new Galaxy S8 has the best smartphone display, awarding it an A+ rating.

Thanks to a new 3K resolution (2960 x 1440 Quad HD+, 570 ppi), blue light filter, support for four different screen modes, plus being the first phone certified by the UHD Alliance for Mobile HDR Premium, Samsung packs a mighty display punch inside of the Galaxy S8 and Galaxy S8+.

As you might already know, DisplayMate doesn’t go handing out A+ grades very often, so it’s a big deal. Stated on their site, “The Galaxy S8 is the first in a new generation of OLED Smartphones that have a Full Screen Display design. It is the most innovative and high performance Smartphone display that we have ever lab tested, earning DisplayMate’s highest ever A+ grade.”

Below, DisplayMate detail everything that has been improved with regard to the display. Not too surprisingly, it’s a long list.
